This toothbrush is going to put a lot of people out of business: It’s got a blue light that activates a tooth-whitening gel … and it really, really works. As in, your teeth noticeably whiten in two days. A month gets your teeth to the whitest they can be (everyone’s “whitest” is different, as any dentist will tell you); then you maintain as you drink coffee, red wine, et al. I couldn’t make it the full month because my teeth became too sensitive. (Just like in-office teeth-whitening! I.e., the stuff really works!) Once they’re sufficiently white, it’s a regular sonic toothbrush, albeit a more bacteria-fighting one because of the blue light. You use regular toothpaste; to whiten (or touch up), you add the gel to your usual paste.
